Abstract: A cellular system transfers a call from a source base-site (200) to one target base-site (205, 210). A source base-site (200) measures the signal strength (RSSIS) of a mobile (225), provides a forecasted signal strength (RSSIF) and sets up two time windows. The source base-site (200) sends the measured and forecasted signal strengths to candidate base-sites (205, 210) found by the mobile (225) which measure the mobile (225) signal strength (RSSIT) and compare it to (RSSIS + hysteresis value). If RSSIT> RSSIS, the call is transferred to the best responding cell. If RSSIT< RSSIS, RSSIT is compared to RSSIF. During this time, the mobile (225) will increase power at the end of the first time window. If RSSIT> RSSIF at any candi-date base-sites (205, 210), the call is transferred to the responding base-site (205, 210). If the source base-site (200) receives no responses during the second time window, the process ends.

Abstract: A magneto-optical recording medium is composed of first through fourth magnetic layers laminated in this order in such a way that an exchange coupling exists between any adjacent layers of the first through fourth magnetic layers so that a magnetization direction can be copied, wherein the first magnetic layer is a memory layer, the second magnetic layer is a writing layer,  the third magnetic layer is a switching  layer,  and  the  fourth magnetic  layer  is  an initializing layer.  Further, respective Curie temperatures Tci satisfy an inequality TC3 < TC1 < TC2  TC4 (i = 1, 2, 3, or 4 indicating an ordinal number of the magnetic layers).          The second magnetic layer exhibits an in-plane magnetization at  room  temperature,   and  exhibits  a  perpendicular magnetization above a predetermined temperature set between the  room  temperature  and  TC3  temperature.    With  this arrangement,  after information is recorded on the memory layer based on the magnetization direction, the interface wall energy can be reduced, and the whole magnetic energy can be made substantially equivalent irrespective of the magnetization condition after recording.   As a result,  a stable  recorded  condition  of  the  memory  layer  can  be achieved.

Abstract: A threaded pipe connection as shown in Figures 1, 4, 5, 6 or 7, having a thread form such as depicted in Figures 8-11, that has: improved sealing; increased resistance to mechanical loads; easy assembly and low makeup torque. Both pin (31) and box (45) may be cut on non-upset pipe ends and result in nearly 100 percent joint efficiency. Tension flank (33) and compression flank (34) may be formed on pin (31) at high flank angles measured from the tubular axis so as to withstand high axial loads without forcing the pin inwardly and the box outwardly, which would tend to separate the mating threads, break the seal and jump threads. Low torque is assured by the complementary forms of pin threads (32) and box threads (42) which confine the thread dope (49) to remain in the root gaps (52) and (54) during assembly.

Abstract: An optical system for monitoring torsional vibration of a shaft (112) has an optical unit (104) including IRLED radiation sources (208) aimed at grid lines (114) applied around the circumference of the shaft (112).  The reflection of the radiation is im-aged through lenses (204) and a matching Ronchi grid (218) onto a photodiode (220) which produces a periodic wave signal from which indications of rotational irregularities can be derived.  In one embodiment, duplicate optical units (104) are arranged in di-ametric opposition across the shaft (112) to compensate for pitch and plunge vibration. In another embodiment, a second dupli-cate optical unit (104) is located at a distance along the shaft from the first unit (104).  The output signals of the two units (104) are passed through a comparator (406), an EX-NOR gate (430) and a low-pass filter (432) to produce a signal indicative of torsional deflection. Also disclosed are a method and apparatus for precisely applying finely spaced grid lines (114) to an existing shaft (112) on site.

Abstract: A fiber mat as well as its method of fabrication and forming machine are described. The fiber mat comprises a plurality of fibers which are limitations bound together and distributed throughout the mat, and wherein some of the fibers are inclined towards a central horizontal plane of the mat. The inclined fibers on opposed sides of the mat have opposed angles of inclination whereby the mat, when used as insulation, can be easily separated substantially along the central horizontal plane by applying a pulling force on one side or opposed sides of the mat in the direction of the inclined fibers. The forming machine is characterized by having two forming surfaces, one disposed horizontally and the other vertically whereby the mat is formed with higher density towards the opposed flat horizontal surfaces of the mat and the lower density is distributed along the central horizontal plane. By having these opposed forming surfaces there is provided a former which provides double formation capacity capable of providing a mat with improved density profile, provides higher air flow, less shingling effect, and the production of a mat which can be easily split substantially in the middle along the central horizontal plane when used as an insulating mat. Because the former doubles the capacity of fibers and also the thickness of the formed mat, it is possible to compress the mat to form fiber boards.

Abstract: An automatic clutch controller for a vehicle that reduces the oscillatory response to clutch engagement. The automatic clutch controller receives inputs from an engine speed sensor (13) and a transmission input speed sensor (31) and develops a clutch actuation signal controlling a clutch actuator (27) from disengaged to fully engaged. The clutch engagement signal at least partially engages the friction clutch (20) in a manner to cause the measured transmission input speed to asymptotically approach engine speed employing an approximate inverse model of this oscillatory response. The automatic clutch controller preferably includes a PID function and a differential engine speed function, which together adaptively adjust clutch engagement corresponding to vehicle loading. The automatic clutch controller includes a PID regulator (65) responsive to the difference of engine speed and transmission input speed, a prefilter (68) operating on the resulting PID signal, and a compensator (70) constructed to reduce the need for detailed particularization for individual vehicles or vehicle models by reducing the system closed loop sensitivity to vehicle parameter variations.
